I've been flashing my hard cock to females in public since I was in my teens.
Your profile says your a teacher, I had one biology teacher in high school that I used to flash regularly since my desk was right in front of her desk.
I'd wear shorts, no underwear and pull up one leg enough to let hang out about two inches of my semi hard cock and she would stare at it all class ha ha.
That went one for about a month when I took It a step much further and stayed after school to visit her classroom and I walked into her empty classroom and when she asked If she could help me with something I openly pulled out my hard cock and balls, started jacking off in front of her while I told her she could help me with this ha ha.
She ended up sucking me off almost every day for 3 months then she suddenly transfered to another school ha ha.
